Infectious arthritis as the single manifestation of sporotrichosis: serology from serum and synovial fluid samples as an aid to diagnosis.

Sporotrichosis is a generally cutaneous, granulomatous, chronic and benign infection. Less frequently the disease may affect the joints. Articular involvement is usually characterized by monoarthritis in the absence of systemic symptoms, generally preceded by skin lesions, and frequently affects immunosuppressed individuals.
